(((Tears))) - so sorry for what you are going through but you are not alone. When I first got here (I'm a recovering addict and recovering codependent) I read a ton of posts by others and realized we have a lot in common.
I know you are feeling overwhelmed right now. Maybe take some deep breaths, do something with the kids? He's not going to change anything until he is ready. I'm sure others will be along with their ES&H (experience, strength, and hope) soon, though it is a little slower on weekends.
Hugs and prayers,
Amy
